When I was knocking around as a kid living in the South I was broke most of the time.. Broke and hot. I remember the yearly chore of installing the window air conditioner. After I slid that dog in the window and turned it on, I was still broke, still hot, and wondering how I was going to pay the electric bill.

 

As you shove an air conditioner into your window to ward off the summer heat, you may wonder why such a small appliance is so incredibly heavy.
